  • Numerical design of a high-flux microchannel solar receiver

    Creator:
    Rymal, Charles
    Abstract:
    This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

  • Numerical response of concrete-lined tunnels crossing active faults

    Creator:
    Lange, Stephanie
    Abstract:
    A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...

  • Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

    Creator:
    Ferreira, Andrew
    Abstract:
    The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...

  • Crystallographic studies of Pyrenophora tritici-repentis ToxA

    Creator:
    Sarma, Ganapathy N.
    Abstract:
    Tan spot of wheat is an economically significant disease caused by the fungal pathogen, Pyrenophora tritici-repentis. Certain races of the fungus secrete Ptr ToxA (ToxA), a 13.2 kDa proteinaceous host-selective toxin that is responsible and sufficient to cause disease in susceptible wheat varieties. Disease symptoms develop only when the ToxA...

  • Effect of high pressure at low temperature on the molecular structure and functionality of dairy proteins

    Creator:
    Walker, Marcia Kaye, 1961-
    Abstract:
    High hydrostatic pressure processing (HPP) is a nonthermal process in which foods are subjected to pressures in the range of 100-700 MPa at room temperatures or higher. HPP is effective in reducing microbial counts and enzyme activity. The ability of HPP to modify the functional properties of proteins has become...

  • Role of post-translational modifications to lens proteins in cataract formation

    Creator:
    Kim, Yung Hae
    Abstract:
    Cataract is a leading cause of blindness throughout the world, yet the fundamental biochemical causes are unknown. A rodent model of the biochemical processes is selenite cataract. This cataract shows some of the features of human cataracts such as increased lens calcium, proteolysis of proteins, and insolubilization leading to lens...

    Creator:
    Tai, Yuan-Ching
    Abstract:
    The adsorption and elution of the antimicrobial peptide nisin at hydrophobic, silanized silica surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]- poly[ethylene oxide] surfactant Pluronic® F108 was measured in situ, with ellipsometry. While such layers are known to inhibit protein adsorption, nisin was observed to adsorb in multilayer quantities, to an...

  • Void fraction variations in a fractal-like branching channel network

    Creator:
    Cullion, Rebecca
    Abstract:
    Two-phase flow in a fractal-like branching microchannel heat sink may have enhanced heat transfer capabilities over single phase flow in the same branching channel network. In order to exploit this potential, a complete understanding of flow boiling in this geometry is required. The fractal-like geometry is similar to that of...

  • Local heat transfer rate and bubble dynamics during jet impingement boiling

    Creator:
    Mani, Preeti
    Abstract:
    Characterization of local boiling trends, in addition to the typically reported area-averaged trends, is essential for the robust design and implementation of phase change technologies to sensitive heat transfer applications such as electronics cooling. Obtaining the values of heat fluxes corresponding to locally varying surface temperatures has been a challenge...
